When is the right time to talk to a youngster about sex?

Do you educate them as soon as possible or wait and let them learn all about it at school to save yourself the embarrassing conversation?
This is the dilemma one mother is facing after her four-year-old daughter developed an interest in the human body - and more specifically an interest in where babies come from.
The young girl has been asking some pretty big questions and her poor mum has no idea how to field them, so she's turned to the internet for advice.
Taking to social media, the mum, Laiste, asked fellow mums whether she was being unreasonable to postpone sex education for her child.
She wrote: "Daughter is OBSESSED at the moment with babies and where they come from.
"She is generally very interested in the body and has a couple of what's inside my body books which she asked for and is fascinated with.
"I'm constantly (and I mean every couple of hours) fielding cheerful questions like 'what's my chin made of?' and 'where is our blood kept?' and 'why don't our eyes fall out?'.
"Alongside this we've had the usual where did I come from questions - always answered honestly by me without leading on too much."
The mum-of-four went on to share some example conversations she'd had with her little one.
This included the mum explaining that babies don't come from the same place food goes and that they grow inside a womb.
For a few weeks this information was enough to satisfy the youngster's curiosity, but soon she was asking questions again.
"How did I get there," she pondered.
Her mum responded by telling her she "grew from a little egg" and that only women have eggs.
But then she wanted to know how she came out of the womb, which was when things took an awkward turn for her mum, who became unsure how much information to disclose.

She decided to tell her she came out through her "flower" which surprised the child, but eventually she accepted it.
The girl then wanted to know when her egg would grow and whether her daddy could help her have a baby like he did for mummy.
"NO!" replied her gobsmacked mum. "Your daddy is your daddy - you'll find someone lovely of your own."
To which her daughter countered: "Will he know where the egg is?"
Feeling flustered, the mum quickly changed the subject.
She ended her post saying: "GOOD GOD! I did not have this with my older three.
"She knows there's a piece of info missing but I daren't start on about penises because we'll never hear the end of it (in Tesco and at school and soft play really loudly probably).
"Am I being unreasonable for holding back a couple of pieces of the puzzle at age four?"
Other parents were quick to sympathise and reveal how they had dealt with similar situations.
One said: "My four-year-old hasn't asked these questions yet. I did get asked what sanitary towels were, so gave a brief child-friendly explanation of periods. I generally try to answer any questions in an honest, child-friendly way.
"If it's something I don't feel comfortable sharing yet, my standard response is: 'It's a bit complicated. I'll tell you when you're older.'"
Another commented: "My boys love the book Mummy laid an egg, has just about the right level of information for that age."
A third added: "Just tell her the truth. She's going to keep asking anyway."
